The PSU is pretty old (2015-16ish, when I got the PC), I don't know the model. The PC still crashes when I run many things, though. It just NEVER crashes while playing games. I am getting a new PC next month, but its very hard for me to work for 1 month coding etc without a pc that can stay on for more than 20 minutes.What is PSU make/model? how old is it?
